At the Windows Live Session event I attended on Tuesday, Phil Holden demoed some new Live Local aerial imagery for the UK, which has now been rolled out. Although its a step forward, we're still lacking the more advanced Birds-Eye feature that exists for many US cities. Imagery for other European citites, including Paris, is expected to be available by the end of the summer.

Update: I've just noticed some of the imagery is pretty old, with buildings that were completed 2 years ago not even showing as construction sites yet. If you're planning to buy a house, don't rely on it to scope out the area!
